The portal 2 Map editor (Beemod) when I import the map into Hammer when I modify even just one wall panel it makes the floor seem intangible making The player fall into nothingness, not even equipped with the portal gun and don;t see any part of the designed map in the start. If you load it without making any hammer edits the maps work perfectly through hammer.
Havnt found any other posts with this problem please if you can help get in contact shortly.
